This invention relates to methods for permanently forming creases in garments such as trousers and has for its object to provide a novel method whereby a crease can be rapidly, accurately and uniformly formed in the garment material.

This and other objects and attendant advantages will become more readily apparent from the detailed description of the invention, reference being had to the accompanying drawing in which Figure 1 is a diagrammatic perspective view showing the method of forming a permanent crease into garments.

Figure 2 is a side elevation of the head of a blind stitch sewing machine provided with means for performing the method of producing the permanent crease in the garment material.

Figure 3 is a partial front elevation and section of the head of a blind stitch sewing machine equipped with means for performing the method of producing the permanent crease into garment material, the section being taken on the line 3x, Bar of Figure 2.

In the several figures of the drawing like reference numerals indicate like parts.

The present invention serves to provide a speedy and accurate method of producing the permanent crease in garments forming the subject matter of Patent No. 2,005,480 June 18, 1935 and in doing so makes such a crease practical and inexpensive in its application to garments and uniform in its appearance thereon.

The apparatus used for performing the novel method of forming the crease may be any of the well known types of blind stitch machines in combination with means which cooperate with the blind stitch forming mechanism to provide the crease and guide the material during the sewing operation.

As described in the patent, above referred to, the crease is formed .and reinforced to permanently hold its form by meansof a tape which is sewed to the inside of the garment material on each side of the crease. My present invention concerns the method of sewing the tape to the garment material and the forming of the crease during the sewing operation in a novel manner so as to accurately produce the permanent crease in the most eff cient manner and at a minimum cost.

The first step in the novel method of producing and permanently holding the crease in the garmerit-material consists in sewing one edge of the reinforcing tape to one side of the crease to be formed or already pressed into the material as indicated in Figure 1. This operation is done on a blind stitch sewing machine which sews the edge of the tape so that a portion of the edge is held against the garment material while the remainder overhangs the crease line or the crease pressed into the garment.

With the tape sewed to the garment material in this manner, the garment is placed in position on the blind stitch sewing machine to have the opposite edge of the tape sewed thereto in the same manner. But before this is done a wire or finger 2 is inserted under the tape adjacent the already sewed and fixed edge of the tape. This wire or finger 2 is thus located on the crease line so that when the garment material is held down over it by the presser foot 3 of the sewing machine mechanism, a crease is formed thereby and held in the garment material at the sewing point of the sewing machine. The plunger 4 of the sewing mechanism operates to one side of the wire or finger 2 to raise the garment material with the edge of the tape to allow the needle to pass thru tape and a portion of the garment material in the forming of the blind stitch which stitches the free edge of the tape to the garment material while a crease is being held in the garment material below the tape substantially centrally thereof.

Where the crease has been previously pressed into the garment material, the finger serves to hold the crease expanded during the sewing operation.

The wire or finger 2 is mounted so as to project in a straight line from the front of the sewing machine under the sewing machine head to have the presser foot 3 thereof hold the tape in place over it with the finger embedded in the garment material. Because of the fact that one edge of the tape is sewed to the garment material alongside of the crease to be formed or already pressed into it as the first step in the forming of the permanent crease, this fixed seam between the tape and the garment material cooperates with the wire or finger 2 to hold the garment material and tape so as to have the sewing machine mechanism perform its sewing operation absolutely parallel to the already fixed edge of the tape and the crease formed in the garment material with relation thereto. This results in the forming of a perfectly straight and uniform crease by the use of the method described.

The depth of the crease is governed by the thickness or diameter of the wire or finger 2 so that by the use of thicker or thinner wire the depth of the crease may be varied.

The wire or finger 2 extends to one side of the sewing machine head at the front thereof and is held in place by a suitable bracket 6 attached to the bed work plate or other portion of the frame of the sewing machine.

We claim:

1. The method of sewing a tape to a garment so as to form and permanently hold a crease in the garment which consists in sewing one side of the tape to one side and parallel to the line of the crease and then depressing the garment material below the central portion of the tape adjacent and parallel to the seam between the tape and the garment while sewing the free side of the tape to the opposite side of the line of the crease.

2. The method of sewing a tape to a garment so as to form and permanently hold a crease in the garment which consists in blind stitching one side of the tape to one side of the line or the crease and then spacing the garment material from the middle of the tape by depressing the garment on a line parallel and adjacent to the blind stitch seam formed between the tape and garment material while blind stitching the free side of the tape to the opposite side of the line of the crease.

3. The method of sewing a tape to a garment having a crease so as to permanently and uniformly fix the crease in the garment which consists in first suitably sewing one side of the tape to one side of the crease and parallel thereto and then uniformly expanding the crease below the tape parallel and adjacent to the seam formed between the garment and the tape while suitably sewing the free side of the tape to the opposite side of the crease.
